Re: Another shuddering/ binding question.

The code 25 is the Torque Control, that cuts the engine power, this can be caused by the connections on the blue/green wires. It can also be because the battery is low in charge, causing the QC to charge slowly. There is a mod to prevent this if it is the problem.

Having said that, the QC won't cause the other problems that you have.
Thanks for the quick reply Harvey. The transmission is from a 98 Leggy outback, not sure of any numbers as it was on the car from the previous owner. And I was pretty sure the QC wasn't the problem as I read a thread about the code and the QC. I did not know about the mod though, I'll look into that and the wires to make sure the connection is true.

Hmm, I'll have to search that as well, thanks.

I noticed it more during traffic and it's more prominent during slow turns under light to heavy acceleration now

Harvey.
Drove around with the fuse in and the problem is still present. Not sure of what my next move should be. Transfer clutch , valves, C solenoid sounds pricey, what's a worst case scenerio with $$$ numbers.
